After my partial drain/fill, done simultaneously, my levels are: FC 7.5, CC 0, pH 7.0-7.7 (reducing it to 7.0 to bring down TA to 60; was 180 at peak), TA 150, CH 900 (was 1500), CYA 50 (was >110+ most likely). I am familiar with the Pool Math site and have been using it. After getting my TA to 60, I will have balanced water by keeping a pH range of 7.2-7.7.
I thought I would be able to say goodbye to the floater with trichlor tablet, but I understand and read some use them when they go on vacations. I read some posts about about maintaining your water and vacations such as http://www.troublefreepool.com/threa...-vacation-plan or http://www.troublefreepool.com/threa...-prep-the-pool. Also, was trying to read about trichlor tablets and CYA in case I had to float those again http://www.troublefreepool.com/threa...or-tablets-add. This vacation will only be 3 days, but I have others planned over the summer for about 1-1.5 weeks.
My plan, at least for this upcoming shorter vacation, is to raise the FC to shock level of 20, based on the aforementioned levels. I don't have a solar cover/blanket, and my pump is controlled by an intermatic mechanical timer. I have it set to run about 4.5 hr from approx 1100-1530 for the solar on the roof. This past weekend temps hit 102 F. I calculated that I lost up to 3.5 ppm of FC; ranged from 2.5-3.5. Yesterday and today, with temps cooler, I only lost 0.5 ppm of FC. FWIW, I don't know anyone who can come over and dump bleach into the pool, or top off the water. But, I think if I bring the water up, it should be okay with evaporation.
Couple of questions:
1. Will this work to maintain my FC level?
2. At the links included in this post, during vacation, people discuss running their pump 24 hr when they bring their FC up to shock level. Is this necessary, or can't it just be run for the standard 4.5 hr I have it set at?
Any help would be greatly appreciated. I have worked way too hard replacing the water and balancing it to let Mr. Algae come over and swim. Thanks for helping me get my pool where it's at and encouraging me to get rid of the pool guy anyway.
